Test Bolus
This is a low dose sequential protocol without table
feed used to calculate the start delay of a spiral scan to
ensure optimal enhancement after the contrast
medium injection. The Dynamic Evaluation function
may be used to generate the time density curve.
You can find the “Test Bolus“ scan protocol in the chap-
ter “Specials“.
How to do it
1.Select the spiral mode that you want to perform, and
then “Append” the Test Bolus mode under Special
protocols.
2.Insert the Test Bolus mode above the spiral mode for
contrast scan by “cut/paste” (with right mouse but-
ton).
3. Perform the Topogram, and define the slice position
for Test Bolus.
4.Check the start delay, number of scans and cycle
time before loading the mode.
5.A Test Bolus with 10 – 20 ml is then administered
with the same flow rate as during the subsequent
spiral scan. Start the contrast media injection and
the scan at the same time.
